Oh awesome, that's nice to see that the Handplane route is so accurate (as usual ! Such a great tool ...)
9thknight : it's actually a little bit more complicated than a just a green channel to flip. At a deeper level, and even with compatible Yup/down, there is a whole bunch of ways to interpret the delicate combination of a model with it's own specific vertex normals, tangents and bitangents + a tangent space normalmap applied to it (basically : there are as many ways to interpret them as there is 3d applications and game engines). While it might not be too noticeable with organic models, these subtle calculation differences create shading artifacts on hardsurface models, as illustrated by the previous screenshot Konras posted.
But thankfully Handplane takes care of this issue, acting like a bridge to generate a normal map perfectly synchronized with a given engine (here UDK) - resulting in the beautifully clean bake Konras just posted.
In short : yay !!
